Description

Technical Field

[0001] The utility model belongs to the technical field of soil restoration, and in particular relates to a fertilizer spreader. Background Art

[0002] In the process of crop planting, in order to improve the growth environment of crops, it is usually necessary to maintain the soil before planting crops. In the face of a large area of ​​planting environment, under the premise of ensuring effective maintenance, the cost of crop planting is reduced. The mixture of livestock manure and straw has become the best choice. Both manure and straw contain rich organic matter and trace elements, such as nitrogen, phosphorus, potassium, etc. After these substances are decomposed by microorganisms in the soil, they can increase the organic matter content of the soil and improve the fertility of the soil. The organic matter in the manure is decomposed by bacteria and fungi in the soil to produce water, inorganic salts and carbon dioxide, thereby improving the soil structure and enhancing the soil's ability to retain fertilizer and water.

[0003] After mixing manure with straw, the mixture is spread on the soil surface through a fertilizer spreader to maintain the soil. However, manure has a certain viscosity. After mixing with straw, they adhere to each other in the barrel of the fertilizer spreader. When the mixture has a high viscosity (i.e. less water content), they adhere to each other in the barrel after mixing to form lumps, causing the outlet of the fertilizer spreader barrel to be blocked, and the fertilizer spreader cannot spread the material normally.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0026] See also Figure 1-Figure 4 As shown, the utility model is a fertilizer spreader, comprising a bracket 1, on which a barrel 2 and a chassis 6 are arranged, the barrel 2 is used to hold mixed organic fertilizer, a discharge port 3 is opened at the bottom of the barrel 2, a fertilizer throwing component 4 is arranged at the discharge port 3, the fertilizer throwing component 4 is arranged on the chassis 6, and a material holding component 5 is penetrated through the middle part of the fertilizer throwing component 4 and slidably installed along the central axis direction of the discharge port 3, so that the fertilizer throwing component 4 and the material holding component 5 can slide relative to each other and rotate synchronously, and a driving component 7 is also arranged on the chassis 6, and the driving component 7 is used to drive the fertilizer throwing component 4 to rotate, and drive the material holding component 5 to slide relative to the fertilizer throwing component 4.

[0027] A connecting piece is also provided on one side of the bracket 1, and the connecting piece is mainly used to install the bracket 1 of the present application on a transportation vehicle. The connecting piece can be, but is not limited to, a hook, a mounting plate (with bolt holes), and other components used for installation.

[0028] Preferably, a hook is provided on one side of the bracket 1, and the bracket is hung on the rear end of a daily vehicle by means of the hook, so that the fertilizer spreader described in the present application is driven by the vehicle to spread fertilizer.

[0029] The fertilizer spreader described in the present application also includes a feeding device, which is arranged at the lower part of the barrel 2 and includes feeding blades. The feeding blades rotate to continuously feed materials to the discharge port while preventing the mixed material from falling. The feeding blades are located above the material collecting component 5.

[0030] First, livestock manure and straw are mixed and put into the barrel 2, and the mixed material is sent to the discharge port by the rotation of the lower material blade. At the same time, the driving component 7 is started to drive the fertilizer throwing component 4 to rotate. The fertilizer throwing component 4 and the material holding component 5 are relatively slidably installed in the direction of the center axis of the discharge port. Therefore, when the fertilizer throwing component 4 rotates, the material holding component 5 is synchronously driven to rotate. Since the driving component drives the fertilizer throwing component 4 to rotate, the material holding component 5 is synchronously driven to rotate relative to the fertilizer throwing component 4. Therefore, when the lower material blade transports the mixed material to the discharge port 3, the mixed material will hit the material holding component 5 in a rotating state, so that the material holding component 5 crushes the mixed material. The continuous up and down movement of the material holding component 5 makes the material holding component 5 fully crush the mixed material and drive the crushed mixed material downward to prevent the mixed material that has not been effectively crushed from blocking the discharge port 3, resulting in failure to spread the material normally.

[0031] The mixed material discharged from the discharge port 3 falls into the fertilizer throwing component 4, and the crushed mixed material is thrown out to the soil surface by the fertilizer throwing component 4.

[0032] In one embodiment, for the above-mentioned fertilizer-throwing component 4, the fertilizer-throwing component 4 includes a throwing bin 401, and the throwing bin 401 is fixedly installed on the chassis 6. A support cylinder 402 is installed on the chassis 6 at the central axis of the throwing bin 401, and penetrates and rotates. One end of the support cylinder 402 located below the chassis 6 is connected to the driving component 7 to drive the support cylinder 402 to rotate, and the other end of the support cylinder 402 is fixedly connected to a fertilizer-throwing leaf 403. A hollow through cavity 404 is provided at the central axis of the fertilizer-throwing leaf 403 and the support cylinder 402, and the two hollow through cavities 404 are connected. A slide groove 405 is provided in the hollow through cavity 404 of the fertilizer-throwing leaf 403, and the slide groove 405 is slidably connected to the material-holding component 5.

[0033] The driving assembly 7 drives the support cylinder 402 to rotate, so that the support cylinder 402 drives the fertilizer-throwing blades 403 fixed thereon to rotate, so that the mixed material dropped from the discharge port into the throwing bin 401 is thrown out through the fertilizer-throwing blades 403 (the throwing-out principle here is mainly centrifugal force, which is a prior art and will not be repeated here), and the fertilizer-throwing blades 403 drive the material-raising assembly 5 to rotate by means of the slide groove 405 on the hollow cavity 404 thereof.

[0034] In one embodiment, for the above-mentioned material-raising component 5 and driving component 7, the material-raising component 5 includes a main shaft 501, the outer surface of the main shaft 501 is in contact with the fertilizing blade 403 and the hollow through cavity 404 of the support tube 402, and one end of the main shaft 501 is provided with a slide bar 502 adapted to the slide groove 405, and the slide groove 405 is slidably matched with the slide bar 502;

[0035] The material-holding assembly 5 further includes a pressing ball 503, which is fixedly mounted on one end of the main shaft 501 and is used to connect with the driving assembly 7;

[0036] An H-shaped frame 8 is fixedly mounted on the lower surface of the chassis 6, the main shaft 501 passes through the H-shaped frame 8, and the main shaft 501 slides relatively with the H-shaped frame 8, and a return spring 504 is fixedly mounted on the upper surface of the pressing ball 503, one end of the return spring 504 away from the pressing ball 503 is fixedly mounted on the H-shaped frame 8, and the return spring 504 is coaxially arranged with the main shaft 501;

[0037] The material holding assembly 5 further includes a material holding parachute tower 505, which is fixedly mounted at one end of the main shaft 501 away from the pressing ball 503, and is located in the inner cavity of the barrel 2 and at the entrance of the discharge port 3;

[0038] The driving assembly 7 includes a motor 701, the motor 701 is fixedly installed on the lower surface of the chassis 6, and a first sprocket 702 and a first helical gear 703 are fixedly installed on the output shaft of the motor 701. The first helical gear 703 meshes with a second helical gear 704, the second helical gear 704 is fixedly installed on the support cylinder 402, the first sprocket 702 is connected to a second sprocket 705 through a chain, the second sprocket 705 is fixedly installed on a camshaft 706, the camshaft 706 is rotatably installed on the H-shaped frame 8, and a cam 707 is fixedly installed on the camshaft 706. The cam 707 is used to squeeze the pressing ball 503.

[0039] When the motor 701 is started, the output shaft of the motor 701 synchronously drives the first sprocket 702 and the first helical gear 703 to rotate;

[0040] The first sprocket 702 drives the second sprocket 705 to rotate through a chain (not shown in the figure). A cam 707 is fixed on the camshaft 706, and the second sprocket 705 is also fixedly installed on the camshaft 706. Therefore, the cam 707 is driven to rotate. The cam 707 is in contact with the pressing ball 503. Thus, during the process of the cam 707 rotating one week, when the longer end of the cam runs upward, the cam 707 squeezes the pressing ball 503, causing the pressing ball 503 to move upward and squeeze the return spring 504. At the same time, the pressing ball 503 drives the main shaft 501 to move upward, so that the material scraping umbrella tower 505 at one end of the main shaft 501 moves upward. When the longer end of the cam runs downward, the longer end of the cam 707 gradually moves away from the pressing ball 503, so that the pressing ball 503 moves downward under the action of the return spring 504, and further the material scraping umbrella tower 505 moves downward, thus realizing the up-and-down reciprocating movement of the material scraping umbrella tower 505 in the material cylinder 2;

[0041] At the same time, the first helical gear 703 drives the second helical gear 704 to rotate, and the second helical gear 704 is fixedly installed on the support cylinder 402, thus driving the support cylinder 402 to rotate, so that the support cylinder 402 drives the fertilizer throwing blades 403 fixed thereon to rotate, and the mixed material falling from the discharge port into the fertilizer throwing bin 401 is thrown out by the fertilizer throwing blades 403; Since the chute 405 is in sliding fit with the slide bar 502, the rotation of the main shaft 501 and the fertilizer throwing blades 403 around their central axis directions is kept synchronous. Therefore, when the fertilizer throwing blades 403 rotate, the fertilizer throwing blades 403 drive the main shaft 501 to rotate synchronously by using the sliding fit of the slide bar 502 and the chute 405. The material scraping umbrella tower 505 is fixedly installed at one end of the main shaft 501, so it synchronously drives the material scraping umbrella tower 505 to rotate;

[0042] The material scraping umbrella tower 505 is in the shape of a "one" character.

[0043] To summarize, the material-raising parachute tower 505 maintains a rotating motion while performing an up-and-down reciprocating motion in the barrel 2, thereby achieving the goal of using the rotating motion to break up the agglomerated mixture, and while it rotates, it reciprocates up and down to fully break up the mixture, and in addition, when it moves upward, the mixture falls to the bottom of the material-raising parachute tower 505 after being broken, and when it moves downward, if there is agglomerated mixture that has not been fully broken up and is blocked at the inlet of the discharge port 3, the material-raising parachute tower 505 will squeeze the mixture downward and squeeze out the mixture, thereby further avoiding blockage of the discharge port and causing the material to be unable to be spread normally, and the up-and-down movement of the main shaft 501 can also bring the mixture at the discharge port downward, thereby reducing the probability of blockage.

[0044] In one embodiment, the lower surface of the fertilizer throwing leaf 403 is combined with the upper surface of the bottom plate 6.

[0045] In one embodiment, baffles 9 are hinged at both ends of the outlet of the swing bin 401, and the output end of the electric push rod 10 is hinged on one side of the baffle 9. The mounting seat of the electric push rod 10 is hinged on one side of the swing bin 401. The baffle 9 is driven to rotate in the swing bin 401 through the output and reset of the electric push rod 10, thereby adjusting the range of material spreading.
